Description
Fremgangsmåte for impregnering av trevirke. Procedure for impregnating wood.
Oppfinnelsen vedrører en fremgangsmåte for impregnering uten oppvarming av tørket trevirke, trefiberplater, tauverk og lignende ved hjelp av vakuum-trykk-behandling, hvor det anvendes en impreg-nerings-sylinder og en lagertank for impregneringsvæske. The invention relates to a method for impregnation without heating of dried wood, wood fiber boards, ropes and the like by means of vacuum-pressure treatment, where an impregnation cylinder and a storage tank for impregnation liquid are used.

løsning i tre har man tidligere gjort bruk av en lukkbar impregneringssylinder som ved hjelp av rørledninger står i forbindelse med en lukket eller åpen forrådsbeholder (lagertank) samt en pumpe. En fremgangsmåte for anordning av sylinder, forrådsbeholder og pumpe fremgår av svensk patent 124 638. Ved hjelp av kjente anord- solution in wood, a closable impregnation cylinder has previously been used which, by means of pipelines, is connected to a closed or open storage container (storage tank) and a pump. A method for arranging the cylinder, storage container and pump appears in Swedish patent 124 638. Using known devices

Slippers og ledningsstolper er de vanligste objekter for disse anlegg som er stasjonære og sjelden varmeisolerte, hvorfor de ikke er i drift om vinteren. Inntrengningen av impregneringsoppløsningen er avhengig av virkets dimensjoner, graden og tiden for vakuum og trykk. lay with large capacity. They are economical for large consumers of impregnated wood. Slippers and cable poles are the most common objects for these facilities, which are stationary and rarely thermally insulated, which is why they are not in operation in winter. The penetration of the impregnation solution depends on the dimensions of the wood, the degree and time of vacuum and pressure.

Ved anleggets mindre dimensjoner fordres kortere impregneringstid, men sett ut fra driftsøkonomisk synspunkt fordres en enklere og mere lettbetjent apparatur. I anordningen ifølge oppfinnelsen fåes et høyt vakuum mellom 75 og 100 pst., hvilket garanterer stor inntrengning av impregneringsvæske i trevirket. Dette forkorter både vakuum- og trykkperiodens lengde samt reduserer det nødvendige trykk. Den første egenskap påvirker driftsøkonomien på en gunstig måte. Den annen egenskap påvirker apparatets dimensjoner og reduserer dermed dets vekt og pris. With the smaller dimensions of the plant, a shorter impregnation time is required, but from an operational economic point of view, a simpler and more easily operated apparatus is required. In the device according to the invention, a high vacuum of between 75 and 100 per cent is obtained, which guarantees great penetration of the impregnation liquid into the wood. This shortens both the length of the vacuum and pressure periods and reduces the required pressure. The first characteristic affects the operating economy in a favorable way. The second feature affects the dimensions of the device and thus reduces its weight and price.
Oppfinnelsen skal beskrives nærmere i forbindelse med tegningene, hvor: Fig. 1 skjematisk viser en anordning ifølge oppfinnelsen. Fig. 2 er en væskelås som inngår i anordningen i fig. 1. Fig. 3 er en del av en silanordning som kan inngå i en anordning ifølge fig. 1. The invention shall be described in more detail in connection with the drawings, where: Fig. 1 schematically shows a device according to the invention. Fig. 2 is a liquid lock which is included in the device in fig. 1. Fig. 3 is a part of a sieve device which can be included in a device according to fig. 1.
I fig. 1 er 1 en impregneringssylinder med en beskikningsluke 2 svingbar med en port 3 til en nedre åpen stilling 4. In fig. 1 is 1 an impregnation cylinder with a coating hatch 2 pivotable with a gate 3 to a lower open position 4.
Impregneringssylinderen 1 er forsynt med en væskestandsniåler 5 og en vakuum-måler 6 samt en trykkmåler 7. En lagertank 8 er anordnet under impregneringssylinderen 1 og er forsynt med en væske-standsmåler 9. Tanken 8 er forbundet med impregneringssylinderen 1 gjennom rør 10 som er forsynt med ventil 11. Tanken 8 er forsynt med en øvre åpning 12 for tilførsel av impregneringsvæske samt tilførsel eller evakuering av luft. Lagertanken 8 er videre forbundet med impregneringssylinderen 1 ved hjelp av en trykkledning 13 i hvilken er innpasset en væskepumpe 14 og en ventil 15. The impregnation cylinder 1 is provided with a liquid level gauge 5 and a vacuum gauge 6 as well as a pressure gauge 7. A storage tank 8 is arranged below the impregnation cylinder 1 and is provided with a liquid level gauge 9. The tank 8 is connected to the impregnation cylinder 1 through pipe 10 which is provided with valve 11. The tank 8 is provided with an upper opening 12 for the supply of impregnation liquid as well as the supply or evacuation of air. The storage tank 8 is further connected to the impregnation cylinder 1 by means of a pressure line 13 in which a liquid pump 14 and a valve 15 are fitted.
Impregneringssylinderen er dessuten forbundet med lagertanken 8 gjennom en vakuumledning 16 i hvilken en sil 17 og en væskelås 18, en ventil 19 samt en væske-strålepumpe 20 er innskutt. Strekete linjer 21 og 22 viser væskenivået i impregneringssylinderen 1, henholdsvis lagertanken The impregnation cylinder is also connected to the storage tank 8 through a vacuum line 16 in which a strainer 17 and a liquid lock 18, a valve 19 and a liquid jet pump 20 are inserted. Dashed lines 21 and 22 show the liquid level in the impregnation cylinder 1, respectively the storage tank

Fig. 2 viser en detalj vedrørende en væskelås 18, hvor 16 er vakuumledningen, som før væskelåsen er gitt en returbøy-ning, og munner ut under en (streket) væskeoverflate 23. Væskelåsens mantel-flate består fortrinnsvis av et gjennomskinnelig rør 24. Fig. 3 er en detalj av en silanordning 17 hvor 16 er vakuumledningen og 25 er selve silen og 26 er rekker av hull i denne. Utgangsstillingen ved impregnerings- prosessen er at man har impregneringsvæske i lagertanken 8 og at man åpner luken 2 og legger inn en mengde virke eller annet materiale i impregneringssylinderen 1, hvoretter luken 2 stenges. På væskestandsmåleren 9 for lagertanken avleses mengden av impregneringsvæske. Deretter overføres væske fra tanken 8 til impregneringssylinderen 1, hvorpå man ved for-nyet avlesning på væskestandsmåleren 9 kan avgjøre hvilken væskemengde som er nødvendig for å fylle ut det luftfylte rom i sylinderen 1. Når sylinderens 1 vakuum er kjent, kan dermed impregneringsvirkets volum utregnes. Dette virke har ofte meget uensartet form, som f. eks. snekkeri- og trevaredetaljer m.v. Etter impregnerings-fremgangsmåtens avslutning kan man ved hjelp av en ny avlesning av væskemåleren 9 fastslå hvilken væskemengde som er blitt opptatt av virket og sammenligne denne mengde med virkets volum, og derved få et mål for impregneringens kvalitet. Impregneringen foregår således at etter at virket er lagt inn i impregneringssylinderen 1 og luken 2 er lukket, startes væskepumpen 14. Ventilen 11 er stengt og ventilen 15 er åpen. Luften i sylinderen 1 evakueres gjennom ledningen 16, tanken 8 og åpningen 12. En viss del av væsken går selvsagt gjennom væskestrålepumpen 20 og ledningen 16 tilbake til tanken 8, Fig. 2 shows a detail concerning a liquid lock 18, where 16 is the vacuum line, which before the liquid lock is given a return bend, and opens out under a (broken) liquid surface 23. The mantle surface of the liquid lock preferably consists of a translucent tube 24. Fig 3 is a detail of a sieve device 17 where 16 is the vacuum line and 25 is the sieve itself and 26 are rows of holes in this. The starting position for impregnation the process is that you have impregnation liquid in the storage tank 8 and that you open the hatch 2 and put a quantity of wood or other material into the impregnation cylinder 1, after which the hatch 2 is closed. The amount of impregnation liquid is read on the liquid level gauge 9 for the storage tank. Liquid is then transferred from the tank 8 to the impregnation cylinder 1, after which, by reading again on the liquid level gauge 9, it is possible to determine what amount of liquid is necessary to fill the air-filled space in the cylinder 1. When the vacuum of the cylinder 1 is known, the volume of the impregnation work can thus be calculated . This work often has a very uneven form, such as e.g. carpentry and woodwork details, etc. After the completion of the impregnation process, a new reading of the liquid meter 9 can be used to determine the amount of liquid that has been taken up by the wood and compare this amount with the volume of the wood, thereby obtaining a measure of the quality of the impregnation. The impregnation takes place in such a way that after the timber has been placed in the impregnation cylinder 1 and the hatch 2 is closed, the liquid pump 14 is started. The valve 11 is closed and the valve 15 is open. The air in the cylinder 1 is evacuated through the line 16, the tank 8 and the opening 12. A certain part of the liquid naturally goes through the liquid jet pump 20 and the line 16 back to the tank 8,
men p.g.a. den betydelige forskjell i areal mellom de to ledninger er denne forbipas-sering praktisk talt uten betydning. Når sylinderen 1 er blitt fylt med impregneringsvæske, stenges ventilen 15, hvorpå væskestrålepumpen 20 settes i virksomhet og pumpen evakuerer da den lille luftmengde som finnes igjen i rørledningen 16. Derved suges den i virket innesluttede luft ut av dette og forlater sylinderen 1 gjennom rørledningen 16. Væskestrålepumper er billige og har meget høy virkningsgrad som ligger mellom 95 og 100 pst. vakuum. Disse høye verdier kan riktignok fåes med andre pumpekonstruksjoner, men til gjen-gjeld er omkostningene slike at de ikke står i rimelig forhold til anleggets totalpris eller verdi. På den annen side er kapasite-ten for væskestrålepumper begrenset hvis man opprettholder kravet til god virkningsgrad. Av den grunn er det hensikts-messig at så lite luftvolum som mulig be-høver å bearbeides av pumpen. Dette mini-mum av luft fåes ved at ifølge oppfinnelsen impregneringssylinderen 1 fylles helt med impregneringsvæske etter at virket er innlagt. Derved er det luftvakuum som skal evakueres bort redusert til den luft but due to given the significant difference in area between the two lines, this passing is practically without significance. When the cylinder 1 has been filled with impregnation liquid, the valve 15 is closed, after which the liquid jet pump 20 is put into operation and the pump then evacuates the small amount of air that remains in the pipeline 16. The air trapped in the work is thereby sucked out of this and leaves the cylinder 1 through the pipeline 16 Liquid jet pumps are cheap and have a very high efficiency that lies between 95 and 100 percent vacuum. These high values can of course be obtained with other pump designs, but in return the costs are such that they are not in reasonable proportion to the plant's total price or value. On the other hand, the capacity for liquid jet pumps is limited if the requirement for good efficiency is maintained. For that reason, it is appropriate that as little air volume as possible needs to be processed by the pump. This minimum amount of air is obtained by, according to the invention, the impregnation cylinder 1 being completely filled with impregnation liquid after the wood has been inserted. Thereby, the air vacuum to be evacuated is reduced to that air
som kan taes ut av virket. For å kunne which can be taken out of the work. To be able to
avlese når evakueringsperioden skal av-brytes, dvs. når ikke lenger luft kan for-late virket i sylinderen 1, er en væskelås 18 innmontert i ledningen 16. Som det to read when the evacuation period is to be interrupted, i.e. when air can no longer leave the cylinder 1, a liquid lock 18 is fitted in the line 16. As it
